ABSTRACT

A contaminação de crianças por chumbo tem sido objeto de investigação no âmbito da saúde pública. Neste estudo avaliou-se o desempenho acadêmico de 102 crianças do Ensino Fundamental. Os participantes foram divididos em dois grupos: um com 34 crianças não contaminadas ou com nível inferior a 5 μg/dl e o outro, de 68 crianças, estava com nível de contaminação por chumbo no sangue entre 10 and 40 μg/dl. Para avaliação foram utilizados o Teste de Desempenho Escolar (TDE) e anamnese. Os resultados indicaram melhor desempenho acadêmico para o segundo grupo, com diferenças significantes em aritmética, leitura e desempenho geral. A comparação entre os sexos indicou melhor desempenho para meninas, dado coerente com a percepção dos pais na anamnese. Embora outras variáveis estejam presentes, os dados apontam prejuízos acadêmicos maiores para crianças com índices de chumbo mais altos. Esses achados requerem políticas públicas para controle da contaminação e redução dos danos em contaminados.


The lead contamination in children has been the subject of research in the field of public health. This study evaluated the academic performance of 102 children from first to fourth grade. The subjects were divided into two groups. The first group was composed of 34 children without lead poisoning or with poison at levels lower than 5 μg/dl. The second group was composed of 68 children with blood lead levels between 10 and 40 μg/dl. The instruments used to evaluate the academic performance were anamnesis and a scholarly performance test called Teste de Desempenho Escolar, TDE. The results indicated better academic performances from the second group with significant differences in arithmetic, reading and general scores. In a comparison between genders, the girls had better performances than the boys. These results were consistent with the parents’ perception in anamnesis. Although other variables were present, the data showed great academic damage for children with higher lead-poison. These outcomes require political policies to control contamination and intervention in this population.

ABSTRACT

AIM: To explore and validate the best returned latent class solution for reading and writing subtests from the Academic Performance Test (TDE). SAMPLE: A total of 1,945 children (6-14 years of age), who answered the TDE, the Development and Well-Being Assessment (DAWBA), and had an estimated intelligence quotient (IQ) higher than 70, came from public schools in São Paulo (35 schools) and Porto Alegre (22 schools) that participated in the 'High Risk Cohort Study for Childhood Psychiatric Disorders' project. They were on average 9.52 years old (standard deviation = 1.856), from the 1st to 9th grades, and 53.3% male. The mean estimated IQ was 102.70 (standard deviation = 16.44). METHODS: Via Item Response Theory (IRT), the highest discriminating items ('a'>1.7) were selected from the TDE subtests of reading and writing. A latent class analysis was run based on these subtests. The statistically and empirically best latent class solutions were validated through concurrent (IQ and combined attention deficit hyperactivity disorder [ADHD] diagnoses) and discriminant (major depression diagnoses) measures. RESULTS: A three-class solution was found to be the best model solution, revealing classes of children with good, not-so-good, or poor performance on TDE reading and writing tasks. The three-class solution has been shown to be correlated with estimated IQ and to ADHD diagnosis. No association was observed between the latent class and major depression. CONCLUSION: The three-class solution showed both concurrent and discriminant validity. This work provides initial evidence of validity for an empirically derived categorical classification of reading, decoding, and writing performance using the TDE. A valid classification encourages further research investing correlates of reading and writing performance using the TDE.
